Cam switch disconnector 20A, switch 0-1 (4-pole), in OB11 housing with lockable front SK20-2.8210\OB11Z

Universal cam switch for demanding applications

This four-pole cam switch with a rated current of 20A is a robust solution for switching electrical circuits. Equipped with a 0 position, it provides safe and convenient disconnection of the load. The OB11 enclosure design with a sealed front guarantees high protection against external factors – the IP65 protection class protects against dust and water jets. It is ideal for both industrial installations and commercial buildings where reliability and safety are required.

Construction and application

The cam switch SK20-2.8210\OB11Z is designed for indirect mounting, although its versatility allows adaptation to different working conditions. Made of durable plastic, it is resistant to mechanical damage and environmental influences. Designed for switching AC-3 circuits with a rated operating power of up to 4 kW at 400V, as well as DC-21A. The switching mechanism based on a knob ensures precision and ease of operation. Thanks to the lack of normally open and normally closed auxiliary contacts, it focuses on the basic function – reliable switching of the load.

Key features and benefits

• High reliability: Continuous rated current of 20A and conventional short-circuit current of 10kA ensure safe operation in harsh conditions.
• Protection against external factors: IP65 protection class guarantees resistance to dust and water, which increases the durability of the device.
• Safety of use: The 0 position allows complete disconnection of the load, minimizing the risk of electric shock during maintenance or repair.
• Versatility: Suitable for a wide range of applications – from simple electrical installations to more complex industrial systems.
• Durability: The enclosure material (plastic) and high quality of workmanship ensure a long service life (mechanical durability: 3 million switching cycles).
• Easy installation: Screw connection of the main contacts facilitates the connection of wires with a cross-section of 1…4 mm².
• Wide operating temperature range: From -40°C to +70°C allows use in various environmental conditions.
